The principal line of worldwide research in this area is the production of crystalline cBN powders of homogeneous structure and with high content of isometric grains. This is due to the necessity of providing guaranteed stability of physical-mechanical and thermal-physical properties, hence, of providing high reliability of tools.

In the Institute for High Pressure Physics, monocrystal cBN powders are produced under high pressures and temperatures with the use of fluid catalyst systems. The powders are comprised of 160/100 and 100/50 m m grain-size monocrystals of tetrahedron shape, ranging in color from colorless to amber, without visible (at 32^x) inclusions. The content of isometric crystals amounts to 20%. The powders are produced in a high pressure apparatus of “CONAC” type, designed in the Institute for High Pressure Physics. The one-cycle yield of the product is 2.5 carats in the reaction volume of 0.7 cm³. Physical-mechanical and thermal-physical properties of the product correspond to the best world’s powders of the same grain-size.
